Definitions

  • the invention relates to a bearing and carrier assembly, according to the preamble of Claim 1.
  • Self-aligning clutch release bearings are generally mounted upon a carrier or sleeve which slides over a shaft or quill during engagement and disengagement of an operatively associated clutch member.
  • An example of such an arrangement is shown in US-A-4,519,488 where a clutch release bearing is mounted upon a carrier with a resilient cap or clip.
  • the clip is formed with openings which engage retaining lugs formed on the carrier.
  • the rolling or deformation of the carrier generally limits the selection of carrier materials to metals.
  • Recent developments have suggested the desirability using plastic materials for forming the carrier, including increased dimensional accuracy, reduced weight and reduced cost.
  • bearing preload is often controlled by the axial pressure generated by a preload element such as a belleville, cone or annular wave spring which is compressed between the radially deformed carrier flange and an axial end surface of a bearing race. Since the bearing preload is quite sensitive to the degree of axial compression of the preload element, minor deviations in the axial location of the carrier flange due to uncontrollable axial tolerances produced during formation of the flange produce large variations in bearing preload thereby leading to unsatisfactory bearing performance.
  • a preload element such as a belleville, cone or annular wave spring
  • Still another problem associated with the formation of a bearing retaining flange by rolling or swaying a radial flange on a metal bearing carrier is the axial and radial dislocation of the preload spring from its intended operational position between the flange and bearing. As the flange is formed, it may cause the preload spring to shift or distort in such a manner that uniform contact between the bearing and washer is lost. This causes an uneven circumferential loading on the bearing which further adversely affects bearing performance.
  • the present invention has been developed to fulfill the needs identified above and therefore has as a primary object the provision of a mounting clip for accurately locating a bearing, preferably a self-aligning bearing, upon a bearing carrier of a clutch release mechanism.
  • Another object is to provide an improved bearing mounting clip having sealing members for retaining lubricant within the bearing as well as between the bearing carrier and the shaft or quill upon which the carrier reciprocates.
  • Still another object is to expedite assembly of a bearing to a carrier member of a clutch release mechanism and to facilitate quality control review of the completed apparatus.
  • Yet another object is to provide a rigid bearing mounting clip which radially supports and strengthens a plastic bearing carrier.
  • FIG. 1 shows a bearing assembly 1 mounted on a carrier member 3.
  • a preferred application of the bearing assembly and carrier is the actuation of a clutch release mechanism associated with an automobile power train. While a self-aligning bearing assembly is shown, any type of bearing having rolling elements retained between bearing races may be used.
  • clutch spring fingers 5 are arranged to contact the bearing assembly 1 while clutch fork 7 is arranged to actuate the carrier 3 in a known fashion.
  • the bearing assembly is connected to the carrier with a rigid clip or bearing retainer 9 so that axial movement of the carrier actuates or axially moves the bearing assembly over a support shaft 45.
  • Clip 9 is generally cylindrical or tubular in shape with a radially outwardly extending flange 11 formed at one axial end portion.
  • Flange 11 is formed for axially engaging and compressing a bearing preload or biasing element such as a wave washer or belleville washer 13, as seen in Figure 1.
  • the flange 11 may be formed as a continuous rim or formed as arcuate circumferentially spaced segments or tabs 10 as shown in Figure 10.
  • the degree of the axial compression of washer 13 determines the bearing preload applied to the inner ring or race 15 of the bearing assembly 1. As indicated above, it is critical to control not only the axial compression of the washer 13 but also to control its alignment and position against the bearing race.
  • clip 9 is preferably formed of a rigid metal material such as C-1010 steel and flange 11 is formed to resist any degree of axial deformation which could significantly affect bearing preload while compressing and retaining washer 13 against race 15.
  • the axial stiffness of flange 11 is achieved by forming the clip with a material thickness of about .38mm and by limiting the radial height of the flange to minimize bending moments about the base 14 of the flange.
  • the axially extending tubular or cylindrical portion 16 of the clip is formed to resist any significant radial compression through use of the materials identified above so that the radial location of the radial innermost surface 12 of the washer 13 is accurately and positively determined.
  • bearing assembly 1 is preferably of the self-aligning variety and is shown as such, the bearing assembly is provided with a degree of freedom to shift or move along a radial plane (vertically as seen in Figure 1).
  • an axially projecting annular stop member 18 limits the radial movement of race 15 to a predetermined extent so that race 15 is prevented from directly radially contacting clip 9.
  • This axial and radial nesting of the clip within an axial end portion of the carrier provides significant radial support to that portion of the carrier which abuts the clip, as best seen in Figure 1.
  • This clip-abutting portion of the carrier is disposed adjacent to and radially inwardly of the bearing assembly. Since the clip is formed of a strong stress-resistant material, the need for additional radial strength or support from the carrier is obviated. This is particularly desirable when the carrier is formed of a plastic material.
  • the clip Since the clip provides substantially all the required strength and rigidity to radially support the bearing assembly, the radial height of the carrier material adjacent the clip may be minimized. Thus, the height H of the carrier which lies beneath or radially inwardly of the bearing assembly can be minimized since its radial support is not required. This arrangement provides greater radial clearance C between the bearing assembly and the carrier.
  • the bearing assembly 1 is free to shift radially with respect to the carrier and quill, as noted above.
  • the clearance C between the bearing and carrier greater design flexibility is afforded since a more radially compact bearing assembly can be designed which provides the necessary radial clearance C for self alignment purposes.
  • the radial height H of the carrier would have to be increased to provide adequate carrier material thickness to support the bearing assembly. This in turn would decrease clearance C and would require the use of a larger bearing. That is, the inner diameter of the bearing would have to be increased to provide sufficient radial clearance C and this in turn would necessitate an increased outer bearing diameter and larger mounting space requirements for the bearing assembly.
  • Clip 9 may extend over the entire axial extent of the bearing assembly 1 so that no portion of the carrier, particularly cantelevered portion 21, need extend axially beneath the bearing assembly.
  • Accurate positioning of the preload element 13 may be further improved by forming flange 11 at a sharp radial break from the outer tubular surface of the clip to provide a sharp 90° angle at 17.
  • the inner radius of curvature at 17 should preferably be limited to a maximum of .127mm to prevent axial and radial sliding movement of the inner surface 12 of the preload washer over the curved portion of the 90° bend.
  • Prior rolling techniques created a large bend radius which allowed axial and radial sliding movement of the preload washer over the arcuate bend surface thereby leading to the problems noted above.
  • At least one engagement recess or window 19 is formed in the clip to receive at least one resilient hook member 21 provided on the carrier. While a single window and hook may be used, a plurality of evenly or symmetrically circumferentially spaced hooks and windows is preferred.
  • the plastic hooks are preferably axially cantelevered from the carrier and terminate in a radial projection 23. While any form of radial abutment or latching surface on clip 9 will suffice for engaging the radial projection 23, a recess is preferred to minimize the radial extent of the main tubular portion of the clip. That is, a radially outwardly projecting ridge on clip 9 would function well, but the increased outer diameter of the ridge could adversely reduce clearance C noted above.
  • the hooks 21 radially deflect against the rigid clip and snap into position within the recesses 19.
  • the distance X from the inner face 25 of each recess 19 to the inner face 27 of flange 11 is accurately controlled during manufacture of the clip to provide the close tolerance necessary for accurate preload control. Tolerances on the order of .05mm should be maintained on dimension X to achieve optimum bearing performance.
  • the carrier 3 is preferably molded of a plastic material, tight manufacturing tolerances on the carrier can be accurately and economically achieved by standard plastic molding techniques. This accuracy is necessary to maintain accurate axial spacing between the outer face 29 of wear plate 31 and the inner face 25 of recess 19 to further ensure desired bearing preload levels. That is, the axial location of race 15 is determined by surface 29 and the axial location of clip 9 is determined by surface 25. The preload element is loaded or wedged between these two elements, and the spacing therebetween determines preload levels.
  • the bearing assembly 1 in Figure 1 is shown with an outer race or ring 33, inner race 15, and rolling element 35 located therebetween.
  • Rear seal 37 and front or nose seal 39 are provided on the races to seal in lubricant and seal out dirt and debris.
  • a radially extending thrust face 41 is formed on the outer race to engage clutch fingers 5.
  • a modified arrangment for nose seal 39 is shown in Figure 3.
  • annular nose seal 39 may be integrated with the clip. This is in contrast to molding the elastomeric material to a separate seal base 32 as in Figure 1. Elimination of separate seal element 39 also removes an additional, although minor, source of tolerance.
  • hook 23 is shown in Figure 2 as pointing radially inwardly, it may alternately be arranged as shown in Figure 3.
  • the hook 23 in Figure 3 is modified in design to point radially outwardly. This modification, by eliminating a separate seal element 39, provides a more axially compact bearing and carrier assembly for use in those applications where axial working clearance is limited.
  • the carrier arrangement shown in Figure 3 provides greater available axial bearing surface support between the inner tubular surface 43 of the carrier and the outer surface 44 of quill 45 than that shown in Figure 1. That is, an additional tubular bearing support surface extends over length D to provide greater radial support to the bearing assembly.
  • a lubricant 47 such as grease or the like is conventionally applied therebetween. After extensive use this lubricant can be lost, or worse, can become contaminated with debris such as friction material abraded from the clutch. This debris then acts as an abrasive which causes rapid wear of both the carrier and quill, leading eventually to failure of the clutch release mechanism through binding of the carrier upon the quill.
  • annular lip 49 may be formed on the clip as seen in Figure 4. As the carrier reciprocates over the quill, annular lip 49 wipes or plows contaminants from the quill surfaces with outer lip face 51 while retaining lubricant within an annular space between the carrier and quill with inner lip face 53.
  • FIG. 5 Another embodiment of the invention is shown in 5 wherein the bearing assembly 1 is clipped to radial flange 55 of the carrier 3. In this arrangement, the axially extending hook 21 projects from the radial outer portion of carrier flange 55.
  • FIG. 6 Still another embodiment is shown in Figure 6 wherein the bearing assembly 1 is not of the self aligning type. Since radial shifting of the bearing does not take place, the bearing assembly 1 may be mounted directly on the clip 9 as shown. Complete radial support for the bearing in thus provided by the clip.
  • the arrangement shown in Figure 7 may have the clip-engaging recesses 57 formed within the carrier 3 and a mating engagement flange 59 provided on the clip.
  • the modified clip for this system is shown fully in Figure 8.
  • the cantelevered portion 63 of carrier 3 shown in Figure 9 is preferably formed to resist deflection during such engagement and to resist fatigue.
  • the resiliency of engagement is provided by the tabs 61.
  • the tabs 61 may be punched or plastically deformed into the recesses after placement of the clip on the carrier.
  • the radially inwardly flexing hook 21 shown in Figure 3 may be replaced with a relatively stiff cantelevered carrier portion 63 and formed with a recess 62 as shown in Figure 11 such that the fingers 61 which may be formed on clip 9 of Figure 3 deflect during engagement rather than the carrier.
  • the clip and carrier engagement arrangement show in Figures 9 and 10 may be directly applied to the bearing and carrier assemblies of Figures 1 and 4-7, just as the engagement arrangement shown in Figures 11 and 12 may be directly applied to the embodiment of Figure 3.
  • any of the clip and window or recess arrangements shown in any of the Figures may be used with any of the embodiments disclosed. All that is required is to match a window formed in one member with a hook or finger formed in the other. Any resilient member may be made rigid as long as its mating member (hook, finger or recess) is made resilient.
  • resilient hooks may be formed on the clip 9 to replace the rigid flange 59 and the windows or recesses 19 may be formed in the carrier such as shown in Figure 7.
  • the hooks or tabs 61 in Figure 10 could alternatively point radially inwardly as shown in Figure 11 and engage a recess formed in the carrier in a similar manner as that shown in Figure 11.
